A Technological Leap…Loquendo TTS delivers the highest levels of flexibility, scalability, performance and robustness;

its multi-threaded, multi-process configuration supports deployment in any high performance software architecture, meeting all your business and technical requirements.

Loquendo TTS has highly performant algorithms and guarantees an extremely rapid response. The speech engine can synthesize different languages and voices simultaneously, switching between them at any time

and on any channel. It is designed for use in any kind of voice application, including highly intensive TTS.The Pronunciation Lexicon ensures that specialized vocabulary, abbreviations, acronyms and even regional

pronunciation differences sound just as the developer intends them to. The characteristics of each voice (i.e. pitch, speaking rate and volume) can be fine tuned and fully controlled. Special formats such as phone numbers, currencies

and e-mail addresses can also be read correctly.Loquendo TTS is available for Telephony, Multimedia and Embedded applications, guaranteeing the same wide range of high-quality voices and languages, all with the same core engine.
